Application :tiled November24, 1909. Serial No. 529,773.

United States, residing at which the following is a specification.

My invention relates to presses such as are used for pressing' out oil or other like materials, and particularly to a rotary press, the object of my invention being to provide an automatic revolving press having self-opening and self-closing press boxes with automatic feed for feeding the oil meal to the press, and an automatic ejector for ejecting the pressed oil cake from the press.

A further object is to of this character, a press box which is closed on all sides while pressure is being' applied to the material opened for the ejection of pressure is relieved.

In general terms, my invention includes a rotatable carrier mounted in a suitable casing and having on its sides a series of press boxes provided with press plates. This carrier revolves so as to bring a plurality of opened press boxes beneath the feeding hop the oil cake, after per, then carries said press boxes in a closed position to hydraulic presses, whereby the oil is expressed, and then carries the press boxes to a point where they are opened, and an ejector operates for the purpose of ejecting the oil cake. The press boxes are arranged in sets around the rotatable press box carrier, and each set is brought successively into position beneath the feeding hopper,

into engagement with the hydraulic press platens, and to the discharge point.

For a full understanding of the invention and the merits thereof, and to acquire a knowledge of the details of construction, reference is to be had tothe following descri tion and accompanying drawings, in whic Figure l is a side elevation of my im? proved oil press; Fig. 2 is an outside face view of the rotatable carrier, the press plates being removed; Fig. 3 is a view looking toward the edge or periphery of the carrier; Fig'. 4 is a horizontal section ofFig. l, through the axis of the rotatable carrier; Fig. 5 is a detail fragmentary perspective of the margin of the rotatable carrier, one of the press plates being removed; Fig. 6 is a fragmentary plan view showing the driving shaft and means for actuating the wrist CURsEY, a

county of' Shelby and State have invented certain new and` useful Improvements 1n Oil Presses, of

provide, in a press within, but is automatically plates; Fig. 7 is a section of shiftable hopper; Fig. 8 is through the valve for hydraulic presses. i

Corresponding and like parts are referred to in the following description and indi cated in all the views of the drawings by the same reference characters. i

Referring to these gures, 2 designates a frame of any desired character and supported in any desired manner, this frame being made preferably as shown in the plan view, Fig. 4, in two parts, bolted together so as to resist lateral pressure. Rotatably supported upon the frame is the shaft 3, which shaft carries upon it the disk or wheel 4c, as shown in Fig. 1l. The outer margin of the wheel is provided with sets of radial headtrees 5, these headtrees being arranged on `opposite sides of the wheel. These trees are arranged in sets of three,

the track and a `detail section operating one of the I the sets being equidistant around the wheel,

and the set of three trees each forming two press boxes 6, the face of the wheel, between the trees, being radially ribbed or corrugated, as at 1l. The press boxes thus formed lare sector-shaped, being larger at their outer extremities than at their inner. This tapering form of the press boxes has an important effect in charging and discharging the press boxes, the press boxes being charged when their larger ends are upward, and ldischarged when the larger ends are downward, thus facilitating the feeding of the press box and the dropping out of the pressed cake.

Extending from the upper portion of the wheel, inV the arc of a circle, and nearly to the lowermost portion of the wheel, is the arcuate abutment or casing 7 which ts the circumference of the wheel closely and closes one end of the space between the headtrees 5 which form the press boxes 6 as the wheel rotates. It will. be seen that before the press box 6 rea-ches the arcuate abutment 7, it is opened at its upper end, as in the position A, for the purpose of receiving a charge of the materialto be pressed. During the passage of the press boxes over the inside face of the arcuate abutment 7, the end of the press box is closed, as before remarked, and when the press boxes have moved past the lower edge of the arcuate abutment, to the position C, theyare opened at their lower` end to permit the pressed cake to be ejected.

Located intermediate of the ends of the described.

`lforced inward bythe pressure a-.proper position.'

but? arey shit-table out'` and in, automatically drawn out of the Apress boxes arcuate abutment 7, and in a position oppov site to that portion of thedisk` or rotatable member 4 in which are the press boxes 6, are opposed pairs of hydraulic presses. The outer cylinders of these presses are designatedbyV the numeral S, the platens by the numeral 9, and the pistons of the platens by the numeral 10. The connections `of these hydraulic presses or rams will be later `As before remarked, these presses are arranged in pairs oneachzside of `the-rotatable carrier t, and. areso arranged that all four of the pressesoperate at one time, two onI each, side of therotatable carr-ier. The .pressure .used with the hydraulic presses willbe accumulated pressure, insuring instantaneous action of the rams.

Supportedbe-tween the headtrees and on Althe faces ofwthe press boxes,are lthe press plates 12. These arepreferablyribbed upon their exterior. surface, for*v ythe purpose .of

.making themlighter, ybut aresmooth upon .theirinteriorffaces rThey. are adapted to be of the .platens hasrotatcd to fThese. press plates are `permanently :carried .within the press boxes, they being 9 when the pressbox carrier when Vtherotatablecarrieris in its loading position and after kthe rotatable y carrier has passedl beyond `the lower .edge of. thesemicircularor arcuate plate' 7 ,v so thatthe cake \may .be ejected. Means for doing this will abe .-lateradescribed. The` circumference of ;the rotatablecarrier .is channeled, as at 13, and this Achannel is formed with Aworm .teeth which `engage-with awormfgear 14 mounted 011; a driving shaft 15. ,The inside face of the. arcuate abutment 7 is also channeled at ,16,'the channel alining with the channel 13,

Ythe two channels'forming means` whereby the oil pressed from the cake between the Ahydraulic vrams l`lor presses will be carried downward and discharged at the lower end of the, arcuate abutment 7.

Mounted .upon `-the inside of the gsupportingfframe, and `surrounding the shaft 3,

are Lthe;A opposed `eceentrics 17, each of ,which is formed-.with an eccentric. groove -18in its face. Mounted in each ofthe press boxes, yand extending through theinnerendthereof,- are the ejectorsV 19 which have the form of plungers, these ,plungers being so shaped as fto-fit vthe inner end ofy the sector-shaped ,press box recess. Theinner ends of the ejectors are, yprovided Iwith laterally projecting studs carrying rollers 2O whicht the cam vtrack of the eccentric 17 xso that as the carrier 4: rotates, the-plungers will be moved inwardly ,or outwardly,

or yheld ystationary by the cam track. The cam track has such .a formthatwhen. any ofthe press boxes arrive-beneath thefilling opening. orin .thepo- 65.- .sition A, vthe ejectorswill be at their .inneru designated 21.

:The pressplates .position until after the press box passes the most position. They will retain this position during the pressing operation, and until they reach the portion of the cam track At this portion of the track, they will be moved outward and act to eject vthe cake from a press box, as shown in Fig.

2. It will be obvious that only a comparatively -smallmovement is necessary to eject the cake, because of the fact that the press box is tapered. 'Thus, as soon as the cake is dislodged, even to a small extent, the cake vwill drop out ,of the box. yhas been ejected .fromthe box, the plunger or After the cake y moved inward. For this purpose, each press plate has-a vgroove `or slot 22 in its edge.

`:This slot is engaged by an linclined rib or cam 23 that begins at `the lower end of the curved abutment 7 and extends around the frame' of the machine. to the position at which the press plate enters between the first ram .or hydraulic press 10. As the earrier 4t rotates past the filling opening, the press plates are held apart, thus giving the press box its maximum capacity. Then, as the press boxes approach the rams, the press plates are moved inward, entirely closing lthe sidesof the press box. l When the press plates reach .the rams, the platens thereof will force the press plates inward, thus pressing the material contained in the press box and forcing the oil or juice out therefrom. are kept in their innermost lower edge of theabutment 7, whereupon thevcamacts to withdraw the press plates outward, enlarging the press box, after vwhich the ejectors act, and the cake drops out as before described.

NVhile I do not wish to limit myself to a l carrier provided with any especial number of press boxes, Ir have shown inthe drawings a rotatable carrier having on each side thereof six press boxes arranged in three pairs, these pairs being equidistantly arranged around the carrier. Thus, the carrier intermittently revolves'through-r a one-third revolution, directing twoof'the boxes on each side directly under the hydraulic rams, two boxes on each side under the filling opening, and the other two boxes on each side to a position where the cake is being ejected. Thus one set of boxes vis always being filled, another pressed, and in. another the cake is being ejected. It

is obvious, however, that I need not arrange these press boxes in pairs, and that I can increaseor decrease the number of press boxes upon the carrier.

For the purpose of giving a rotation to the rotatable carrier, I have shown the worm shaft l5 above referred to, but I do not wish to be limited to this means of rotating the carrier, as it is obvious that many different means may be provided for rotating the press box carrier, or movement through a a revolution.

While I may use any form of feeding device found applicable for the purpose, I preferably use a movable hopper or cartike receptacle 25 which o crates between a meal heater and the feeding opening, whereby the press boxes are lilled. This hopper is preferably formed of a casing having no bottom but supporting longitudinally to the middle portion of the hopper and at the lower end thereofI the triangular' supporting member 27. This supporting member rests upon a triangular rail 28 having the laterally projecting flanges 29. I/Vhen the hopper is upon this rail and over the laterally projecting flanges 29, the flanges form the bottom of the hopper so that the bottom is closed. The flanges 29 arecut away at the points when the hopper comes to a position over the carrier, the sides of the hopper will be open at the bottom, and material will be guided down by the triangular median member 27 to the opposed press chambers 6. Means for loperating the movable hopper' will be later described.

As a means for driving the various parts heretofore described, I provide a main drive shaft 40 which is continuously operated from the driving pulley 4l. This shaft is mounted in any suitable manner and carries upon it the loose. gear wheel" 42 havin@4 thereon the clutch member 43. Slidably mounted on the shaft 46 by means of a spline or feather predetermined part of clutch member the shaft 40. by means of a lever mounted on a bracket 46. Fast upon a shaft l5 is the gear wheel 48 which meshes with the gear wheel 42 so that when the wheel 42 is rotated with the shaft 40, the wheel 48 will be rotated with the shaft 15. This shaft carries upon it the worm 14 which engages with the rotatable carrier, thus be seen that when the gear 42 is connected to the shaft 40, the carrier will be rotated, and when disconnected, the carrier will be held from rotation.

50 designates a shaft which is rotated at the same speed as the shaft 40 and by any desired mechanism, as by the pulley 5l.

43 and which rotates with `able clutch member giving it a step-by-step` 30 and 3l so that is the shiftable clutch i member 44 which is complementary to the This member 44 is shifted as heretofore described. It will` This shaft carries upon it the "cam disk 52 formed with a cam track 53 which engages a lilik 54, this link'being connected to the lever 45 so that as the cam revolves, the lever will be held stationary until the offset portion of the cam isreached, when the lever will be reciprocated to force the mov- 44 into engagement with the member' 43. The cam 52 is so timed that it will rotate three times to each complete rotation of the carrier 4 and its shaft 3. By this means, the carrier 4 is given intermittent rotary movement so that each set of press boxes is brought in front of the hydraulic presses and held there while these presses operate, and after the operation, the carrier is again rotated.

It will be seen that the sets of press boxes are so arranged relatively to each other that when one set of press boxes is in front of the hydraulic presses or rams, the other presses will be in position to receive material from the hopper 25. Mounted upon the shaft 50 and rotating therewith, are the cam disks 55 and 56, each of which is connected by a link 57 to a wrist plate 58. Each wrist plate has upon it the oppositely located projecting studs 60 and 6l. A link 62 extends from the stud 60 to the valve-operating arm 63 of one hydraulic press cylinder, while the stud 61 is pivotally connected to the link 64 which extends to the arm 65 of the other hydrauliccylinder on the same side. `It will be seen that there are two cams 55 and 56 and two wrist plates 58, and that each wrist plate is connected by two links 62 and 64 to the valves ofthe hydraulic cylinders on that side of the carrier. The cylinder of each press has projecting from it the pipe 70, and rotatably mounted in 4said pipe. is the valve 7l (see Fig. 8). Leading from said pipes are the inlet pipe 72 and the outlet pipe 73. When the valve is turned in one direction, the pipe is connected to the inlet pipe 72, while when turned in the opposite direction it is connected to the outlet pipe 73. The cams 55 and 56 are precisely the same as the cam 52, but these cams 55 and 56 are set a little in advance of the cam 52 so that the outlet valves will open just before the rotation is given to the carrier and so that the inlet valves will be opened just after the carrier has been brought to a position of rest. Also mounted upon the shaft 50 is the toothed gear 75 which meshes with a gear wheel 76 on a shaft 77, which shaft carries upon it the crank disk or crank 78 to which is connected the link 79 which is pivotally attached at its other end to the hopper 25. Thus, as the disk 78 rotates, the hopper will be carried from the meal heater to a point immediately above the carrier.` This reeiprocation of the hopper will occur three times for each complete rotation of the car- Cil ESGE

automatically filled, Vand automatically opened to :the ribbed iimer vare automatically filled from the top, and

- ger whereby the pressed cake lis forced out,

thereby, theyare closed at the outer end `nated by the numeral 80, which will carry rier 4,. and Ais so timed that the hopper .will l arrive over the discharge opening B0 to the carrier just after the chambers 6 have arrived thereunder.

The operation of my invention will be obv-ions from what has gone before, and it will be seen Athat my pressis entirely automatic iny its action; that the press boxes are automatically closed permit the ejection of the cake; that the oil or other liquid expressed fromthe meal or other material will be forced out and will run down faces of the press boxes to the inside face of the curved abut-ment 7, and will be carried down the channel of this abutment 7 anddelivered at the bottom yof the abutment, and that the oil will conftinue'to drop or run off from the lower 4end of the press ybox asV soon as the press .box passes the lower end of the abutment 7.

vThe advantages of my invention are, first, that it does not require a press cloth to be iisedysecond, that `it saves the labor of removing thepress cloth from the oil cake,` as well as saving the use of the press cloth. The press .boxesl are soformed that they the ejector-operatesso as to from the-bottom, where they are assisted by gravity and their-own weight to easily drop from the press box. rIhe ejector forms the bottom of -the press box as well as the plunej ect the cakes while when the press :boxes are moving tothe hydraulic rams and being engaged by the curved abutment 7 which alsoI acts asl the `means for conducting the oil to the point of delivery. After thepressed cake is forced out, it-is preferably deposited upon a conveyer of any suitable kind, desigthe compressed cake away from the machine.
